I've made 10+ orders from QDS over the past year or so, so will chime in with some feedback.
Labeling: when ordering raws, they are sometimes labeled in such a way where you have to decipher what raw powder is what. Clearer labeling (although I understand the need for discretion) would be helpful.
Orals: Although the price is always right for orals, I wish the tablets were pressed/packaged better. If I order 100 tablets, I can be sure that about 15-20 of them will be broken and there will be a significant amount of dust at the bottom of the bag. I'm not sure if this is a problem with pressing (needs better binder, more pressure, etc.) or packaging (maybe needs desiccant pack in the bag?), but it's annoying. I can't bitch too much considering the price.
Quality: Based purely on fEeLz, most of the products are properly dosed. However, a few things I bought I think might be *slightly* underdosed and maybe one item significantly underdosed. The sildenafil tablets and tadalafil tablets seem weaker than the Indian generics I buy. The semaglutide, for sure, is not nearly as good as an Ozempic pen. I've tried alternating my QDS semaglutide and Ozempic and I always get a reaction from the Ozempic pen (nausea, lack of appetite lasting for days, etc.), but not much from QDS. Again, take this with a grain of salt--maybe a lab analysis would prove me wrong.
However, overall the process is very easy, straightforward, they offer a decent value. Hope they expand their US offerings.
